Cafes, Opéra/Grands Boulevards
Fodor's Review:
To join the latest generation of trendy flaneurs (wanderers), take a break opposite the Rex Cinema, at De la Ville Café. Look for the Belle Epoque details -- this was once a high-end bordello -- but choose a seat facing the boulevard, so you can watch the passersby.
